Overall Structure Section 5-1
5-1-1 PLC Interface Area
Words are allocated in the Special I/O Unit Area of the CPU Unit.
The CS1W-MC421 is allocated 50 words and the CS1W-MC221 is allocated
30 words.
Note 1. The CS1W-MC221 is allocated the words for three unit numbers in the
above area and the CS1W-MC421 is allocated the words for five unit num-
bers. The numbers following that of the set unit number are also allocated
to the MC Unit.
2. Because the CS1W-MC221 is allocated three unit numbers, it cannot be
assigned unit numbers 94 and 95.
3. Because the CS1W-MC421 is allocated five unit numbers, it cannot be as-
signed unit numbers 92 to 95.
4. Make sure that the same unit numbers are not used by other Special I/O
Units.
5-1-2 Data Transfer Words
The first word for transfer is designated in the INTELLIGENT I/O WRITE
(IOWR) or INTELLIGENT I/O READ instruction. When data is transferred
between the CPU Unit and the MC Unit, only words for the amount of data
transferred are used.
Refer to
Section 4 Data Transfer and Storage for details on the data transfer
words.
